I personally love to read books that take me into a world that I'll never have a chance to live in. One of those books I thoroughly enjoyed was Complications by Atul Gawande. He talks candidly about what it's like for a doctor to learn medicine.
Dr. Gawande recently published the story The Cost Conundrum in The New Yorker where he explores why the Medicare Costs in McAllen Texas are so much higher than the national average. It's not a quick read, but it is a fascinating analysis that I hope you'll enjoy.
